“The aspheric design of this multifocal IOL enhances patients’ outcomes”, says Elizabeth A. Davis, MD. “There are a number of different IOLs to choose from to achieve the best outcome for patients today. Presbyopic correction lenses are now available and with good results. In many cases, surgeons prefer the Tecnis Multifocal IOL (Abbott Medical Optics Inc. [AMO]) based on their design and positive outcomes.”
In assessing any IOL, you must consider several factors: ease of implantation, predictability of refractive outcome, quality of vision, range of focus (spectacle independence), patients’ satisfaction, side effects, and long-term stability.
The Tecnis Multifocal IOL is based on an aspheric optic design meant to reduce the spherical aberration of an average cornea to zero. The Tecnis Multifocal has a full-diffractive posterior surface, which makes the diffractive optics pupil independent for optimal image quality at all distances under any lighting condition. The optic is made of acrylic and comes in both a one- and three-piece design. The frosted edge also minimizes edge glare.

In a clinical trial, 94.6{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of subjects implanted bilaterally with the lens reported being satisfied with their vision. Also at 1 year, 92.1{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of the subjects had 20/25 or better distance UCVA and saw 20/32 or better at near with distance correction in place. More than 86{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} of subjects reported never wearing glasses, and slightly less than 90{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} were able to function comfortably without glasses at all distances (96.9{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} at near, 89.7{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} at intermediate, and 95.5{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} at distance).Only 1{0730eed075b45d9e50c00d6cd42dd08773e0164f29a45151808bf89051290974} always wore glasses.
所有多焦点IOL固有地减少对比度并诱导一定数量的眩光和光晕，重要的是要通知所有患者，他们应该预期这种副作用。使用TECNIS多灶性IOL实现最佳的折射结果，需要仔细的术前，术中和术后护理。术前制备需要优化眼表，这是一项彻底检查，以排除具有良好结果的疾病的患者，并精确的生物特征和IOL计算。
为了通过镜头取得最佳效果，选择合适的候选人很重要。当然，患者应希望减少对眼镜和隐形眼镜的依赖。他们不仅应该了解白内障手术的风险，而且还应该了解镜头的潜在副作用，包括减少对比度，眩光和光晕。患者应具有最小的角膜散光，或者外科医生应该有一种适当的方法来管理散光。准确的术前角化测量和生物识别测量至关重要，必须对眼表疾病进行积极治疗。
Presbyopia-correcting IOLs are one of the most important transforming factors in the practice of anterior segment ophthalmology, and the AcrySof IQ Restor (Alcon Laboratories, Inc.) diffractive multifocal lens is the most commonly implanted presbyopia-correcting IOL in the United States. This technology offers patients visual rehabilitation for functional distance, reading, and intermediate vision. The surgeon’s selection of patients, meticulous attention to detail, and optimization of postoperative results are the keys to successful outcomes with this lens.
激光性白内障手术技术的最新进展可能会使囊核仁糖具有更大的核心和稳定的尺寸，从而可以通过长期纠正的IOL来增强折射结果。具有Iolmaster（Carl Zeiss Meditec，Inc。）或Lenstar LS 900（Haag-Streit AG）和散光的控制精度生物特征量对于最大化结果也是必不可少的。由于必须仔细地将晶状体常数个性化给个别外科医生，因此跟踪术后结果对于完善手术结果至关重要。
Patients are incredibly sensitive to small refractive errors with presbyopia-correcting IOLs, so surgeons must be willing and able to treat them. Astigmatism of greater than 0.50 D in a symptomatic patient requires surgical planning.
与残余屈光不正,the ocular surface,2 cystoid macular edema, and the posterior capsule, surgeons can improve appropriate patients’ quality of vision with the AcrySof IQ Restor IOL. The technology has enhanced the quality of life of many pseudophakic patients by reducing or eliminating their need for spectacles. As physicians’ comfort with multifocal lenses improves in the coming years, these IOLs should become more popular, both with cataract and refractive surgeons and their patients.
